    <!-- The <b class="button">Build Circuit</b> button will construct a circuit whose gates correspond to the currently chosen expressions for each output. The circuit's inputs and outputs will be displayed in top-down order corresponding to how they appear under the Inputs and Outputs tabs. Generally speaking, the constructed circuit will be attractive; and, indeed, one application of Logisim's Combinational Analysis module is to beautify poorly drawn circuits. Still, as with any automatic formatting, it will not express the structural details that a human-drawn circuit would. -->
    <b class="button">
     构建电路
    </b>
    按钮将构建一个电路，其门对应于当前为每个输出选择的表达式。 电路的输入和输出将以自上而下的顺序显示，对应于它们在“输入”和“输出”选项卡下的显示方式。 一般来说，构建的电路会很有吸引力； 事实上，Logisim 组合分析模块的应用之一就是美化绘制不佳的电路。 尽管如此，与任何自动格式化一样，它不会表达人工绘制电路所表达的结构细节。

    如果您键入现有电路的名称，则该电路将被替换（在 Logisim-evolution 提示您确认确实要执行此操作之后）。

    <b class="propertie">
     构建电路
    </b>
    对话框包含两个选项。
   </p>
   <ul>
    <!-- <li>The <b class="button">Use Two-Input Gates Only</b> option specifies that you want all gates constructed to have two inputs. (NOT gates, of course, constitute an exception to this rule.) -->
    <li>
     <b class="button">
      仅使用两个输入门
     </b>
     选项指定您希望所有构建的门都具有两个输入。 （当然，“非”门构成了该规则的一个例外。）
    </li>
    <!-- <li>The<b class="button">Use NAND Gates Only</b> option specifies that you would like it to translate the circuit into one using only NAND gates. You can select both options if you want to use only two-input NAND gates. -->
    <li>
     <b class="button">
      仅使用 NAND 门
     </b>
     选项指定您希望将电路转换为仅使用 NAND 门的电路。 如果您只想使用双输入 NAND 门，则可以选择这两个选项。
    </li>
   </ul>
   <p>
    <!-- Logisim cannot construct a NAND-only circuit for an expression containing any XOR operators. This option will therefore be disabled if any outputs' expressions contain XORs. -->
    Logisim-evolution 无法为包含任何 XOR 运算符的表达式构造仅 NAND 电路。 因此，如果任何输出的表达式包含 XOR，则该选项将被禁用。
